● Carbon anode material
The negative electrode materials that have been actually used in lithium ion batteries are basically carbon materials such as artificial graphite, natural graphite, mesocarbon microbeads, petroleum coke, carbon fiber, pyrolytic resin carbon and the like.
● Tin-based anode material
Tin-based anode material can be divided into two kinds of tin oxide and tin-based composite oxide. Oxides are the oxides of various valence metallic tin. There is no commercial product.
There are no commercial products either.
● Alloy category
Including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, and also no commercial products.
Carbon nanotubes, nano-alloy materials.
At present, according to the latest developments in the market of lithium battery new energy industry in 2009, many companies have begun to use nano-titanium oxide and nano-silica added in the traditional graphite, tin oxide, carbon nanotube inside, greatly improving the charge of lithium battery Discharge and charge and discharge times.
